OIII AND ACID FEEDING- DEVICE FOR FLOTA'IION' PROCESSES.

To all whom it may concern Be it known that I. WILLIAM 1V. VOL- com, a citizen of the United States, and a resident of Georgetown. in the county of Clear Creek and State of Colorado, have invented a new and useful Improvement in- Oil and Acid Feeding Devices for Flotation Processes, of which the following is a specification. t 7

My present invention relates generally to .oil. flotation processes of ore extraction and is more particularly a machine'for feeding oil or acids in small and definite quantities to the flotation machines in such processes,

.my object being the provision of a simple,

inexpensive machine for feeding materials of the above nature with a definite regularity at all times and at various temperatures, and one which may at the same time be read ly and quickly adjusted to maintain regularity of feed, in accordance with deft .nite quantities over a wide range determined for the most part upon the amount of ore handled.

-Machines for the present purpose have been before PI0IT)"i8(l and are in fact now in use, ranging down from more or less complicated devicesto a can or vessel with a drain cock through which the liquid is permitted to slowly drip. For various reasons such machines and devices have. fallen short of giving a regular feed at all temperatures, which is vital in flotation processes and therefore in proposing the present construction my invention aims to reduce variation of feed to a minimum and at the same time provide for a wide range of feed change along with simplicity and accuracy.

In the accompanyin .drawing illustrat ing a construction em odying my present invention,

Figure 1 is a top plan view.

Fig. 2 is a rear elevation on a reduced scale, and

Fig. 3 is a side view.

Referring now to these figures, my improved construction embodies a supporting frame, 10, in connection with which an 01 or acid receptacle 11, i bolted or may be formed integral, said receptacle 11, opening upwardly and having an inclined drip an, 12, extending partially thereover, w ose depending flange, 13, 1s bolted thereto as seen in Fig. 3, and whose outer portion is seen in Fig. 1.

ment of which may be effected by winged adjusting bolts, 17, bearing against the journal boxes and threaded through the rearmost extremities of the said extensions.

Through the journal boxes, 16, is extended a shaft, 18, having pulleys, 19, at one end for the reception of a belt as seen in Fig. 3 connecting the same with a suitable source of power, and between the extensions of the bracket, 15, this shaft has a friction disk, 20, secured upon a sleeve, 21, the latter of which is adjustably held upon the shaft by a set screw, .22.

The bracket 15 supports at its center bearings, 23, for a shaft, 24, extending at right angles with respect to the shaft 18, and provided upon its rear end with a friction wheel, 25, normally engaged by the friction disk. 20, and across whose working face the said friction disk is adjustable in order to vary the speed of movement of shaft, 24, with respect to that of shaft 18.

Upon its forward end shaft, 24, has an enlarged carrier disk or wheel, 26, whose front face is parallel and adjacent to the rear straight edge, 27. of the drip pan, 12, and whose diameter is preferably slightly greater than the width of the drip pan at its said rear edge.

Around its peripheral edge the carrier wheel, 26, supports a plurality of bolted clips, 28, in which a series of cups, 29, open at one end in the direction of rotation of the carrier wheel, are supported. These cups may be of a suitable nature, as for instance, empty brass cartridge shells, and are, on account of their particular support, readily renewable. and interchangeable as to particular size and capacity.

ceptacle so that during its rotation the cups fill at the lower portion of the wheel and empty onto the drip pan, 12, at the upper portion of the wheel, without the danger of discharging any of the oil or acid clinging to the wheel itself, the several buckets of the carrier wheel projecting laterally and forwardly therefrom as shown.

It is obvious that with cups or buckets of known capacity and with the means shown, consisting of a friction wheel, 25, and an adjustable friction disk, 20, the speed of |movement of shaft, 24, may {be quickl changed to give any definite range or fee and it is equally obvious that in any adjusted position, or in other words, at any range of feed, extreme regularity will be maintained and variation of feed reduced to a minimum.

It is furthermore obvious that in addition to its extreme accuracy, my invention is susceptible of a wide range of use where v a regularity in the feed of oils and acids is desired, and is in addition, simple, inexpensive, and will be durable in use.

I claim:

1. In a device of the character described the combination of a frame, a fluid receptacle carried by the frame, a bracket mounted on the frame, and having extensions projecting away from the said receptacle, adjustable bearings carried by the extensions of said bracket, a shaft mounted in said bearings, a friction disk adjustably secured upon the shaft, a second shaft journaled on the bracket at right angles to the first shaft, a friction Wheel at one end'of said second shaft normally engaged by the said friction disk, a bucket wheel mounted upon the other end of the second shaft and extending into the fluid receptacie, a series of buckets carried by said wheel and projecting laterally therefrom, and a drip pan mounted contiguous to the bucket wheel and onto which the buckets discharge as described.

2. In a device of the character described, the combination of a supporting frame, a fluid receptacle carried by the frame, a bracket mounted on the frame and having spaced apart extensions projecting, away from the said receptacle, and provided'with upturned extremities, beari s carried by the said extensions .of said brac et, bearing adjustment screws threaded through the upturned ends of the extensions and engaging the said bearings to shift the latter, a shaft mounted in said bearings, a friction disk mounted on the shaft and adjustable therealong, a second shaft journaled on the bracket parallel to the extension thereof and at right angles to the first mentioned shaft, a friction Wheel mounted upon the ends of said second shaft adjacent to the first shaft, a bucket, wheel mounted upon the opposite end of the second shaft and extending into the fluid receptacle, a series of buckets carried by said wheel and projecting laterally therefrom, and a drip pan mounted contiguous to the bucket wheel and onto which the buckets discharge, as described.
